SummaryCropping systems research to improve the productivity of an acid upland rice and maize-based farming system is described and evaluations by co-operating farmers are presented. Farmers rejected introduced patterns. The cropping choices of non-cooperating farmers are described in terms of cost–benefits and the reasons underlying their decisions. An approach that combines an understanding of farmers' systems in order to conduct focused research on the weak points of such systems, together with an evaluation of farmer technology and adaptation, may be more effective than researcher-designed, farmer-implemented cropping pattern trials.

Abstract kadon, daud d. 2019.Productivity and ecological sustainability of upland rice farming in the province of maguindano.Doctoral dissertation. Graduate school, university of southern mindanao, kabacan, cotabato. 184 pp. Major adviser: palasig u. Ampang, ph.d. The research study was conducted to determine the productivity and ecological sustainability of upland rice farming system in the province of maguindanao. One hundred three (103) farmers from 26 barangays of the province constituted the respondents. Descriptive statistics, correlation and multiple regression statistical tools were utilized. The test of hypotheses was set at 5% level of significance. The results revealed that upland farmers were generally males, married and were at least in their early 40s and finished intermediate education a family size ranging from 4 to 6 members had an income within the bracket of php 62,000 to 111,999 engaged in farming for a period of 17 to 24 years and were tilling 1 to 2 hectares of land but were non-members of agriculture-related organizations/association and had no trainings attended. Credit accessibility was never accessed rolling land was devoted to upland rice production. Tenurial status and membership in organization were found best significant predictors of the productivity of upland rice farming while age, civil status and number of trainings attended were found best significant predictors of ecological sustainability of upland rice farming. The socio-economic environment such as the source of information was found as the best significant predictors of the productivity of upland rice farming in the province of maguindanao. On bio-physical environment, soil type and cultural measure were found to have a significant influence on the productivity of upland rice farming in the province of maguindanao while level of destruction of insects, pests, diseases, rodents, birds and wild animals, seed selection, cropping pattern, cultural measure, mechanical measure and management of rice stubbles after harvest were found to significantly influence on the ecological sustainability of upland rice farming in the province of maguindanao.

SummaryThe radical concept of potato production from true potato seed (TPS) was adopted as a component of their farming system within three seasons by 23 farmers from Cibodas, West Java. The farmers showed an ability to conceptualize and experiment and desired concepts from which they could develop, through research, appropriate principles and field techniques. Information received solely as detailed practices or techniques hindered their progress, since they first needed to repeat the technique in order to understand the concepts and principles involved. Farmer experimentation resembled closely that of experimental station researchers, with the use of replication in space, often neighbouring farmers' plots, and time. Initial experiments covered a wide range of factors but within three seasons farmers had identified similar areas of concern which coincided with those of experiment station researchers worldwide. Farmer experimentation and the role of the researcher in this methodology for technology development are discussed.

The effects of earthworm inoculation and cropping systems on upland rice systems were examined over a four-year period in the Highlands of Madagascar. Each year, endogeic earthworms Pontoscolex corethrurus (Rhinodrilidae) were inoculated (EW+) at a density of 75 ind m−2 or were not inoculated (EW0). Inoculation was tested in three cropping systems: conservation agriculture (CA) and traditional tillage with or without residues restitution. Soil and plant properties were measured during the first three years while soil biological properties were assessed at the fourth year. At the end of the experiment, earthworm density was three-fold higher in EW+ than in EW0, demonstrating the success of the inoculation. Earthworm density was more important in CA than in tillage systems. Earthworm inoculation had higher significant effects on soil and plant properties than cropping systems. Earthworm inoculation had positive effects on soil macroaggregation (+43%), aboveground biomass (+27%), rice grain yield (+45%), and N grain amount (+43%). Intensifying earthworm activity in field conditions to meet the challenge of ecological transition is supported by our study.

The research aims to: (1) identify the income differences between Aloe vera farming system with monoculture and multicultural cropping pattern; (2) identify the risk of cost, production, and income of Aloe Vera farming of each cropping pattern, (3) identify farmer behavior to the risk of each Aloe Vera farming system, and (4) determine socio-economic factors influencing the farmer behavior to the risk of Aloe Vera farming .. Research area was chosen by purposive in North 'Pontianak sub-district, West Kalimantan. Analyses used were cost and income analysis, coefficient of variation analysis, quadratic utility function, and multiple linear regressions. The results show that the Aloe Vera farmer income with monoculture cropping pattern is lower than Aloe Vera farmer with multicultural. The risk of cost, ,production, and income of Aloe Vera farming with monoculture cropping pattern is higher than multicultural. 40.74% Aloe Vera farmers with monoculture cropping pattern and 7.89% Aloe Vera farmers with multicultural show behavioral risk lover. There are 14.82% Aloe Vera farmers with monoculture cropping pattern and 28.95% Aloe Vera farmers with multicultural show behavioral risk averse. The remaining were risk neutral farmers, i.e. 44, 44% Aloe Vera farmers with monoculture cropping pattern and 63,16% Aloe Verafarmers with multicultural. Farmer behavior to the risk influenced by farmer's age, family size, farmer's experience, and dummy of cropping pattern and farmer ethnical.

<p>ABSTRACT</p><p><br />Development of Rainfall and Runoff Harvesting Technology: Farming System Analysis of<br />Water Resources Utilization. Application of rainfall and runoff harvesting in dry land could be increasing the availability of water resources, extending the growing season, and reducing the risk of loss yield. To create a sustainable water management, farmers participation were needed in its management. The objectives of the research<br />were to study the impact of rainfall and runoff harvesting technology applications (channel reservoir) on farming system and to study the farmers perception on the existence of channel reservoir.The study was conducted in Limampoccoe village, Cenranae subdistrict, Maros distrisct, South Sulawesi province, from February to October 2012. The research was conducted by several steps namely: 1) the application of rainfall and runoff harvesting<br />technology through channel reservoir, 2) analysis of the farming system and assessment of the farmer perception on the existence of channel reservoir. Result of the research showed that rainfall and runoff harvesting technology have been increasing the cropping intensity by changing the previous cropping pattern from rice-fallow-fallow into ricepeanuts-<br />fallow and rice-watermelon-fallow. There was an increase in farmers' income after channel reservoir built and the farmers will be taken the responsibility to maintain the continuity of the channel reservoirs function.</p><p><br /><em>Keywords: </em>rainfall and runoff harvesting, cropping intensity, farmers’ income</p><p><br />ABSTRAK</p><p><br />Aplikasi teknologi panen hujan dan aliran permukaan di lahan kering dapat meningkatkan ketersediaan air, memperpanjang masa tanam, dan menekan risiko kehilangan hasil.
